We can do a 200 or even 500 encounter test to increase the sample size, like how the other Pokemon Wikis check the rarity of wild Pokemon before they somehow get their hands on official rarity information, but it is extremely time-consuming and troublesome to do so.

I'd agree with Mario, getting info directly from the developers is the only way to end this issue once and for all. Unfortunately, it is true that they won't leak these info easily. If anyone is willing to do the 200 encounter test and provide a report via the blog or discussion board here, however, I'll be very, very, very grateful.
